Abstract

Abstract:

BACKGROUND: By using the bone filling mesh container, a small amount of bone cement can be penetrated to the trabecular space to form a microscopic twist, thereby strengthening the vertebral body. But there is no report about bone filling mesh container for treatment of osteoporotic vertebral compression fractures.

OBJECTIVE: To compare the vertebral uplift and cement leakage of bone filling mesh container, percutaneous vertebroplasty and percutaneous kyphoplasty for the treatment of wedge-shaped osteoporotic vertebral compression fractures.

METHODS: Ninety patients with wedge-shaped osteoporotic vertebral compression fractures were randomly divided into three groups. Polymethylmethyl acrylic bone cement type II was perfused into these three groups by bone filling mesh container, percutaneous vertebroplasty and percutaneous kyphoplasty, respectively. Bone cement type, vertebral uplift, leakage rate, visual analogue scale score, Oswestry disability index and Cobb’s angle were calculated and compared among the three groups.

RESULTS AND CONCLUSION: The operation was successful in all patients. The success rate of puncture was 100%. There were 2 cases of bone cement leakage for percutaneous vertebroplasty and one case for percutaneous kyphoplasty. The vertebral uplift, visual analog scale score, Oswestry disability index and Cobb’s angle were improved significantly in the three groups after treatment (P < 0.05). Percutaneous kyphoplasty and bone filling mesh container were superior to percutaneous vertebroplasty on the aspect of vertebral uplift and kyphosis correction (P < 0.05), but there was no significant difference between the former two groups (P > 0.05). No difference in pain relief and action recovery was found among the three groups. These findings demonstrate that the bone filling mesh container with polymethylmethyl acrylic bone cement for treatment of osteoporotic vertebral compression fractures can have a promising result in relieving the pain, lifting the injured vertebral height, and the correction of kyphosis, which can also reduce the leakage rate of bone cement.
